A quick search on Cars.com shows there are dealers around the country who have new ones. The problem that you might run into is supply and demand. Now, that they've stopped production, the dealers will try and use that to jack up the prices. If you are serious, you're going to have to do a good amount of research and negotiating! Good luck.
